30 Claims.

The invention relates to brake rigging for railway car trucks and hasreference, particularly to a beamless type of rigging, having associatedtherewith that type of brake in which a brake shoe is applied toopposite sides of a car wheel and known as a clasp brake.

One of the objects of the present invention is to provide a type ofbrake rigging especially adapted to meet service conditions prevailingin railway motor trucks, wherein it is necessary to provide sufiicientspace for parts attached to the underframe.

-Yet another object is to provide a brake rigging in which the livetruck levers are so connected to the'truck and to the brake rigging thatshould certain links or connections fail, the leverswill not fall on thetracks.

Still another object is to provide in a brake system of thetypevdescribed, release mechanism which will allow eilicient operationof the brakes but which will, after application of the brakes,

' serve to return the operating, parts of the rigging to releasedposition.

A still further object of the invention is to pro-l vide in a brakesystem as described, a release mechanism adapted to return the operativeparts of the mechanism to release position, which will be springactuated and of extreme simplicity in construction. l

A yet further object is to provide a brake rigging of simpleconstruction which will be light in weight and effective and positive inoperation.,

With these and various other objects in view, the invention may consistof certain novel features of construction and operation, .as will bemore fully described and particularly pointed out 'in the specification,drawings and claims appended hereto.

In the drawings, which illustrate an embodiment of the device andwherein like reference characters are used to designate like parts-Figure 1 is a fragmentary top plan view of a railway car truck equippedwith brake rigging em the invention;

rFigure 2 is a fragmentary side elevation of the construction shown inFigure l;

Figure 3 is a top plan view of a railway car truck showing theapplication thereto of a brake system embodying the invention;

Figure 4 is a side elevation of the truck construction and brake riggingshown in Figure 3; Figure 5 is a transverse fragmentary sectionalvelevation of the brake rigging taken substantially in the plane of thetransverse center line of 'the truck;

(ci. lss-56) The railway car truck 10 may be oi any con- 65lstruction,'being provided with the end connecting members 12 and thetransoms 14 disposed between the side frames 16. The side frames areprovided with the depending pedestal jaws 18 adapted to have cooperativeengagement with the usual journal boxes or other journal means of thewheel and axle assemblies 20. Suitable equalizers 22 are shown asprovided between said journal boxes.

'I'he brake rigging includes the dead truck levers 75 24 pivoted tosuitable brackets`26 as at 28, said brackets being provided on the endtransverse connecting members 12, preferably in the plane of the wheels.Suitable brake heads 30 provided with shoes 32 are pivoted as at 34 tothe truck levers 24 80 intermediate the ends thereof, and the brakeheads on opposite sides of the truck are connected and spaced by brakehead tie'straps 35. The

'lower ends of said truck levers are pivotally mounted as at 36 to theslotted heads 38 of the 85 slack adjuster pull rods 40 disposed belowthe axle or wheel centers, the slack adjuster 42 being disposed on theheads thereof.

The inner ends of the pull rods 40 are pivotally connected as at 44 tothe lower ends of the live 90 truck levers 46, said levers on oppositesides of the truck being connected and spaced by the .tie straps 47. Thelive truck levers are provided with brake heads 48 provided with thebrake shoes 50, the brake heads being pivotally connected as at 52 tothe live truck levers 46 intermediate the ends thereof and to the endsof thefbrake hangers 54, said brake hangers being pivoted as at 56adjacent the upper ends thereof to the car truck. The upper end ofthelive truck lever 46, disposed at the left end of the truck as viewed inFigures 3 and 4, is pivoted as at 58 to the links or clevises 60 whichare pivoted as at. 62 to the inner end of the equalizing lever 64.

The equalizing lever 64 is a dead lever, being se- 105 lectively pivotedas at 66 to the strap links 68 of the fulcrum bracket 70 secured to theside frame, the outer end of the equalizing lever 64` is selectivelypivoted as at '72 to the pull rod '74,

the other end ofthe pull rod being pivoted as truck lever 46 disposed atthe right of the truck.

The live equalizing lever 78 -is pivoted inter.-

mediate the ends thereof as at 86 to the pull rod I 88, the opposite endof said pull rod being pivtermediate the ends thereof. The outer. end ofsaid fulcrum lever is pivoted as at 94't'o the fulcrum bracket 96disposed on. the side frame and provided with the fulcrum lever support97. The inner end of the fulcrum lever is pivoted as at 98 to pull rod100 which is pivoted as at 102 to the horizontal equalizer 104 carriedon the support 105 secured to the car underframe and provided withsuitable means 106 for connection to a hand operated brake operatingmeans or topower operating means.

AThe pull rod 88 is provided with the bracket 108 disposed adjacent thelever 78, said bracket being provided with a release spring rod 110slidably mounted in the release spring bracket 112. The spring 114 isdisposed between the bracket 112 and the washer or head 116 provided onthe release spring rod 110, the spring Y114 being a compression springand normally urging the brake rigging toward the left as viewed in vtheiigures.- that i's, toward release position.

1n order to apply the brakes, therefore, operation of the hand or powermeans moves the horizontal equalizer 104 toward the right as viewed inthe iigures, causing the pull rod 100 to move the fulcrum lever 92 in aclockwise direction about the pivot 94. Movement of the fulcrum lever 92exerts a pull on the pull rod 88, compressing the spring 114 and bodilymoving the live equalizing lever 78 on its supporting bracket 79 towardthe right. Movement of the equalizing lever '78 toward the right causesthe upper end of the live truck lever 46 at the right to move to applyits brake shoe to the Wheel and axle assembly.

Continued movement causes the live truck lever 46 to pivot around thepoint 52 to cause the lower end thereof to move' toward the left or in aclockwise direction whereby the pull rod will be moved toward theleft tomove the dead truck lever 24 at the right of the figure to apply itsbrake shoe. The ,said continued movement of the equalizing lever 78causes a pull on the pull rod 74, moving the dead fulcrum lever 64 c ina counter-clockwise direction around the pivot 66. This movement causesthe upper end of the live truck lever 46 at the left to move to applyits brake shoe to its associated wheel.

Continued movement of the live truck lever causes a'pivotal movementaround its pivot 52 to movev its associated pull rod 40 `toward theright as viewed in the iigure whereby the dead truck lever 24 at l`theleft of the gures moves in a counter-clockwise direction to causeengagement between its brake shoe andthe associated wheel. Release of'the hand or power operated means permits the spring 1 14 to'move the pun'rod as toward the left as viewed inthe figures to cause release of thebrake rigging in amanner opposite to that described for setting;

It is to be understood that 1 do not wish to be limited. by the exactembodiment of the device shown, which is merely by Way of illustrationand not limitation, as various and other forms of the device'will ofcourse be apparent to those skilled in the art Without departing fromthe spirit of the invention or the-scope of the claims.
